Scandir() will be close when it iteration is over.You can see ScandirIterator_iternext:

```
static PyObject *
ScandirIterator_iternext(ScandirIterator *iterator)
{
    while (1) {
        ...
    }
    /* Error or no more files */
    ScandirIterator_closedir(iterator);
    return NULL;
}
```

So, `entries = list(scandir(parent_path))` resources in this code can be properly closed.
